Calycogonium Rhomboideum
''Calycogonium'' (common name, angleflower) is a polyphyletic genus of about forty species in the family Melastomataceae, native to the Caribbean, particularly Hispaniola, Jamaica, and Cuba. The genus is a member of a clade characterized by calyptra on flower buds, few hairs, and the presence of mite domatia on the underside of the leaves.

Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...
